Will it be open to app developers?

When the iPhone first launched, developers couldn't make apps for it. All you got were the apps that came with the iPhone out of the box.

Now the question is whether or not Apple will take the same approach for the iWatch. Will developers be able to write apps for the gadget? Or will they have to wait until the iWatch gains more traction?

Will it come in different color options?

Since smartwatches are always exposed, it makes sense for them to come in a variety of color options.

Will Apple allow you to swap the band for a different color? Will the gadget itself come in different colors? Today's smartwatch color options are pretty limited.

Will it work without your iPhone?

Smartwatches today only have limited functionality unless they're paired to your smartphone using Bluetooth. How will Apple's iWatch handle being tethered to the smartphone? What will it be able to do on its own?

Will the battery last longer than a day?

Most color screen smartwatches have trouble lasting longer than a day on a single charge. If you're going to have a gadget strapped to your body all day, it'd be annoying to charge it before the sun even sets.

If the iWatch is going to be a success, it'll need good battery life.

How will you charge it?

Speaking of battery life, the iWatch will need an easy way for users to charge it up. Today's smartwatches have clunky charging methods. For example, Samsung's Gear watches require you to attach a dongle before charging with a regular USB cord.

A wireless charging solution, which would let you place the watch on a charging pad, would make much more sense.
